The Mumbai civic body's education department has said that controversial preacher Zakir Naik's Islamic International School (IIS) in South Mumbai is operating without authorisation.

Brihanmumbai Municipal Corporation's South Mumbai region education inspector B B Chavan, in a letter issued on Wednesday, stated that no school can run without the NOC (no objection certificate) of the local governing body, as defined under provisions of the Right to Education Act, 2009.

It was also mentioned in the letter that parents should not enrol their children in IIS.

However, it was not specified in it if the school has obtained the NOC.

Meanwhile, Samajwadi Party MLA Abu Asim Azmi, who recently took over the school, alleged that "there was a conspiracy to harass" the institution's management.

"The school is being run on the same lines (as earlier) with only some changes, including in its name and management. I have taken the premises on rent and have done nothing to invite the fury of the education department," said Azmi, who is the legislator from Mumbai's Mankhurd Shivaji Nagar Assembly constituency.

However, he also said that the school management would get in touch with the education department and find out if any more permissions are required to run it.

"I would not want any controversy. Neither me nor the education department would want to jeopardise the future of the students. Therefore, I have asked our team to get in touch with the education officers and obtain all the required permissions," Azmi said.

Notably, the Maharashtra government had in December last year informed the parents of the students of IIS that it would either be shut or brought under a new management.

Azmi had last year requested the Maharashtra government not to close down the Islamic Research Foundation (IRF)-run school saying doing so will jeopardise the future of students enrolled there. He had made the request to state Education Minister Vinod Tawde.
